I need to find a single foot to fit a Volvo square load bar, of the style that is locked onto the rail using a long torx with the little torque guage. Somehow, these feet don't do well when your wife drives over the bar on the ground. Anyone got an orphaned single bar, etc? Damaged bar? The foot just slides off the end of the square bar when the locking system is loose. These are the ones that fit into a slot on the underside of the bar, not the kind that the bar slides through a square opening.
